They lose tackiness after a few weeks and become less grippy. They get a discoloration as mentioned on the killerspin website. They are extemely light. They are great shoes and have a good amount of grip, still, just not as much from the beginning. Another problem is that I have around a size 10.5 US or 11 foot and since the largest size of this shoe is 9.5, it kind of squeezes my foot :)
